FIG. 1 is a block diagram of a mobile terminal 100 in accordance with one exemplary embodiment.

The mobile terminal 100 may comprise components, such as a wireless communication unit 110, an Audio/Video (A/V) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, a power supply 190 and the like. FIG. 1 shows the mobile terminal 100 having various components, but it is understood that implementing all of the illustrated components is not a requirement. Greater or fewer components may alternatively be implemented.

Hereinafter, each component 110 to 190 is described in sequence.

The wireless communication unit 110 may typically include one or more modules which permit wireless communications between the mobile terminal 100 and a wireless communication system or between the mobile terminal 100 and a network within which the mobile terminal 100 is located. For example, the wireless communication unit 110 may include at least one of a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short-range communication module 114, a location information module 115 and the like.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel.

The broadcast channel may include a satellite channel and a terrestrial channel. The broadcast managing entity may indicate a server which generates and transmits a broadcast signal and/or broadcast associated information or a server which receives a pre-generated broadcast signal and/or broadcast associated information and sends them to the mobile terminal. The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. The broadcast signal may further include a data broadcast signal combined with a TV or radio broadcast signal.

Examples of broadcast associated information may include information associated with a broadcast channel, a broadcast program, a broadcast service provider, and the like. The broadcast associated information may be provided via a mobile communication network, and received by the mobile communication module 112.

The broadcast associated information may be implemented in various formats. For instance, broadcast associated information may include Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), Electronic Service Guide (ESG) of Digital Video Broadcast-Handheld (DVB-H), and the like.

The broadcast receiving module 111 may be configured to receive digital broadcast signals transmitted from various types of broadcast systems. Such broadcast systems may include Digital Multimedia Broadcasting-Terrestrial (DMB-T), Digital Multimedia Broadcasting-Satellite (DMB-S), Media Forward Link Only (MediaFLO), Digital Video Broadcast-Handheld (DVB-H), Integrated Services Digital Broadcast-Terrestrial (ISDB-T) and the like. The broadcast receiving module 111 may be configured to be suitable for every broadcast system transmitting broadcast signals as well as the digital broadcasting systems.

Broadcast signals and/or broadcast associated information received via the broadcast receiving module 111 may be stored in a suitable device, such as a memory 160.

The mobile communication module 112 transmits/receives wireless signals to/from at least one of network entities (e.g., base station, an external mobile terminal, a server, etc.) on a mobile communication network. Here, the wireless signals may include audio call signal, video (telephony) call signal, or various formats of data according to transmission/reception of text/multimedia messages.

The mobile communication module 112 may implement a video call mode and a voice call mode. The video call mode indicates a state of calling with watching a callee's image. The voice call mode indicates a state of calling without watching the callee's image. The wireless communication module 112 may transmit and receive at least one of voice and image in order to implement the video call mode and the voice call mode.

The wireless Internet module 113 supports wireless Internet access for the mobile terminal. This module may be internally or externally coupled to the mobile terminal 100. Examples of such wireless Internet access may include Wireless LAN (WLAN) (Wi-Fi), Wireless Broadband (Wibro), Worldwide Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA) and the like.

The short-range communication module 114 denotes a module for short-range communications. Suitable technologies for implementing this module may include BLUETOOTH™, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee™, Near Field Communication (NFC) and the like.

The location information module 115 denotes a module for detecting or calculating a position of a mobile terminal. An example of the location information module 115 may include a Global Position System (GPS) module.

Still referring to FIG. 1, the A/V input unit 120 is configured to provide audio or video signal input to the mobile terminal. The A/V input unit 120 may include a camera 121 and a microphone 122. The camera 121 receives and processes image frames of still pictures or video obtained by image sensors in a video call mode or a capturing mode. The processed image frames may be displayed on a display unit 151.

The image frames processed by the camera 121 may be stored in the memory 160 or transmitted to the exterior via the wireless communication unit 110. Also, user's position information and the like may be calculated from the image frames acquired by the camera 121. Two or more cameras 121 may be provided according to the configuration of the mobile terminal.

The microphone 122 may receive an external audio signal while the mobile terminal is in a particular mode, such as a phone call mode, a recording mode, a voice recognition mode, or the like. This audio signal is processed into digital data. The processed digital data is converted for output into a format transmittable to a mobile communication base station via the mobile communication module 112 in case of the phone call mode. The microphone 122 may include assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.

The user input unit 130 may generate input data input by a user to control the operation of the mobile terminal. The user input unit 130 may include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, a jog switch and the like.

The sensing unit 140 provides status measurements of various aspects of the mobile terminal. For instance, the sensing unit 140 may detect an open/close status of the mobile terminal, a change in a location of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, the location of the mobile terminal 100, acceleration/deceleration of the mobile terminal 100, and the like, so as to generate a sensing signal for controlling the operation of the mobile terminal 100. For example, regarding a slide-type mobile terminal, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include sensing functions, such as the sensing unit 140 sensing the presence or absence of power provided by the power supply 190, the presence or absence of a coupling or other connection between the interface unit 170 and an external device.

The sensing unit 140 may include a proximity sensor 141, a stereoscopic touch sensor 142, an ultrasonic wave sensor 143 and a camera sensor 144. The sensing unit 140 may be implemented as a three-dimensional (3D) sensor which detects a location of a moving object (hereinafter, referred to ‘target to be sensed’), which is present in a 3D space. Here, the target to be sensed, for example, may be a user's body (e.g., finger), an accessory or the like.

The output unit 150 is configured to output an audio signal, a video signal or a tactile signal. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153 and a haptic module 154.

The display unit 151 may output information processed in the mobile terminal 100. For example, when the mobile terminal is operating in a phone call mode, the display unit 151 will provide a User Interface (UI) or a Graphic User Interface (GUI), which includes information associated with the call. As another example, if the mobile terminal is in a video call mode or a capturing mode, the display unit 151 may additionally or alternatively display images captured and/or received, UI, or GUI.

The display unit 151 may be implemented using, for example, at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-Liquid Crystal Display (TFT-LCD), an Organic Light-Emitting Diode (OLED), a flexible display, a three-dimensional (3D) display, an e-ink display or the like.

Some of such displays 151 may be implemented as a transparent type or an optical transparent type through which the exterior is visible, which is referred to as ‘transparent display’. A representative example of the transparent display may include a Transparent OLED (TOLED), and the like. The rear surface of the display unit 151 may also be implemented to be optically transparent. Under this configuration, a user can view an object positioned at a rear side of a terminal body through a region occupied by the display unit 151 of the terminal body.

The display unit 151 may be implemented in two or more in number according to a configured aspect of the mobile terminal 100. For instance, a plurality of the displays 151 may be arranged on one surface to be spaced apart from or integrated with each other, or may be arranged on different surfaces.

Here, if the display unit 151 and a touch sensitive sensor (referred to as a touch sensor) have a layered structure therebetween (referred to as a ‘touch screen’), the display unit 151 may be used as an input device as well as an output device. The touch sensor may be implemented as a touch film, a touch sheet, a touchpad, and the like.

The touch sensor may be configured to convert changes of a pressure applied to a specific part of the display unit 151, or a capacitance occurring from a specific part of the display unit 151, into electric input signals. Also, the touch sensor may be configured to sense not only a touched position and a touched area, but also touch pressure. Here, a touch object is an object to apply a touch input onto the touch sensor. Examples of the touch object may include a finger, a touch pen, a stylus pen, a pointer or the like.

When touch inputs are sensed by the touch sensors, corresponding signals are transmitted to a touch controller. The touch controller processes the received signals, and then transmits corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched.

Still referring to FIG. 1, a proximity sensor 141 may be arranged at an inner region of the mobile terminal 100 covered by the touch screen, or near the touch screen. The proximity sensor 141 may be provided as one example of the sensing unit 140. The proximity sensor 141 indicates a sensor to sense presence or absence of an object approaching to a surface to be sensed, or an object disposed near a surface to be sensed, by using an electromagnetic field or infrared rays without a mechanical contact. The proximity sensor 141 has a longer lifespan and a more enhanced utility than a contact sensor.

The proximity sensor 141 may include a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and so on. When the touch screen is implemented as a capacitance type, proximity of a pointer to the touch screen is sensed by changes of an electromagnetic field. In this case, the touch screen (touch sensor) may be categorized into a proximity sensor.

Hereinafter, for the sake of brief explanation, a status that the pointer is positioned to be proximate onto the touch screen without contact will be referred to as ‘proximity touch’, whereas a status that the pointer substantially comes in contact with the touch screen will be referred to as ‘contact touch’. For the position corresponding to the proximity touch of the pointer on the touch screen, such position corresponds to a position where the pointer faces perpendicular to the touch screen upon the proximity touch of the pointer.

The proximity sensor 141 senses proximity touch, and proximity touch patterns (e.g., distance, direction, speed, time, position, moving status, etc.). Information relating to the sensed proximity touch and the sensed proximity touch patterns may be output onto the touch screen.

The audio output module 152 may convert and output as sound audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. Also, the audio output module 152 may provide audible outputs related to a particular function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer or the like.

The alarm unit 153 outputs a signal for informing about an occurrence of an event of the mobile terminal 100. Events generated in the mobile terminal may include call signal reception, message reception, key signal inputs, a touch input etc. In addition to video or audio signals, the alarm unit 153 may output signals in a different manner, for example, using vibration to inform about an occurrence of an event. The video or audio signals may be also outputted via the audio output module 152, so the display unit 151 and the audio output module 152 may be classified as parts of the alarm unit 153.

The haptic module 154 generates various tactile effects which a user can feel. A representative example of the tactile effects generated by the haptic module 154 includes vibration. Vibration generated by the haptic module 154 may have a controllable intensity, a controllable pattern, and so on. For instance, different vibration may be output in a synthesized manner or in a sequential manner.

The haptic module 154 may generate various tactile effects, including not only vibration, but also arrangement of pins vertically moving with respect to a skin being touched (contacted), air injection force or air suction force through an injection hole or a suction hole, touch by a skin surface, presence or absence of contact with an electrode, effects by stimulus such as an electrostatic force, reproduction of cold or hot feeling using a heat absorbing device or a heat emitting device, and the like.

The haptic module 154 may be configured to transmit tactile effects (signals) through a user's direct contact, or a user's muscular sense using a finger or a hand. The haptic module 154 may be implemented in two or more in number according to the configuration of the mobile terminal 100.

The memory 160 may store a program for the processing and control of the controller 180. Alternatively, the memory 160 may temporarily store input/output data (e.g., phonebook data, messages, still images, video and the like). Also, the memory 160 may store data related to various patterns of vibrations and audio output upon the touch input on the touch screen.

The memory 160 may be implemented using any type of suitable storage medium including a flash memory type, a hard disk type, a multimedia card micro type, a memory card type (e.g., SD or DX memory), Random Access Memory (RAM), Static Random Access Memory (SRAM), Read-Only Memory (ROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Programmable Read-Only Memory (PROM), magnetic memory, magnetic disk, optical disk, and the like. Also, the mobile terminal 100 may operate a web storage which performs the storage function of the memory 160 on the Internet.

The interface unit 170 may generally be implemented to interface the mobile terminal with external devices. The interface unit 170 may allow a data reception from an external device, a power delivery to each component in the mobile terminal 100, or a data transmission from the mobile terminal 100 to an external device. The interface unit 170 may include, for example, wired/wireless headset ports, external charger ports, wired/wireless data ports, memory card ports, ports for coupling devices having an identification module, audio Input/Output (I/O) ports, video I/O ports, earphone ports, and the like.

The identification module may be configured as a chip for storing various information required to authenticate an authority to use the mobile terminal 100, which may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), and the like. Also, the device having the identification module (hereinafter, referred to as ‘identification device’) may be implemented in a type of smart card. Hence, the identification device can be coupled to the mobile terminal 100 via a port.

Also, the interface unit 170 may serve as a path for power to be supplied from an external cradle to the mobile terminal 100 when the mobile terminal 100 is connected to the external cradle or as a path for transferring various command signals input from the cradle by a user to the mobile terminal 100. Such various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal 100 has accurately been mounted to the cradle.

The controller 180 typically controls the overall operations of the mobile terminal 100. For example, the controller 180 performs the control and processing associated with telephony calls, data communications, video calls, and the like. The controller 180 may include a multimedia module 181 which provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180 or as a separate component.

The controller 180 can perform a pattern recognition processing so as to recognize writing or drawing input on the touch screen as text or image.

The controller 180 may also execute a lock state in which a user is restricted from inputting a control command for applications when a state of the mobile terminal meets a set condition. Also, the controller 180 may control a lock screen displayed in the lock state based on a touch input sensed on the display unit 151.

The power supply 190 provides power required by various components under the control of the controller 180. The provided power may be internal power, external power, or combination thereof.

Various embodiments described herein may be implemented in a computer-readable medium using, for example, software, hardware, or some combination thereof.

For a hardware implementation, the embodiments described herein may be implemented within one or more Application Specific Integrated Circuits (ASICs), Digital Signal Processors (DSPs), Digital Signal Processing Devices (DSPDs), Programmable Logic Devices (PLDs), Field Programmable Gate Arrays (FPGAs), processors, microprocessors, other electronic units designed to perform the functions described herein, or a selective combination thereof. In some cases, such embodiments are implemented by the controller 180.

For software implementation, the embodiments such as procedures and functions may be implemented together with separate software modules each of which performs at least one of functions and operations.

The software codes can be implemented with a software application written in any suitable programming language. Also, the software codes may be stored in the memory 160 and executed by the controller 180.

Hereinafter, description will be given of a communication system operable with the mobile terminal 100 according to the present disclosure.

FIGS. 2A and 2B are conceptual views of a communication system operable with the mobile terminal.

First, as illustrated in FIG. 2A, communication systems utilize different air interfaces and/or physical layers. Examples of such air interfaces utilized by the communication systems include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS), the Long Term Evolution (LTE) of the UMTS, the Global System for Mobile Communications (GSM), and the like.

Hereinafter, further description will relate to a CDMA communication system, but such teachings may be applied equally to other system types including the CDMA wireless communication system.

Referring to FIG. 2A, a CDMA wireless communication system is shown having at least one mobile terminal 100, at least one base station (BS) 270, at least one base station controller (BSC) 275, and a mobile switching center (MSC) 280. The MSC 280 is configured to interface with a conventional Public Switch Telephone Network (PSTN) 290. The MSC 280 is also configured to interface with the BSCs 275. The BSCs 275 are coupled to the base stations 270 via backhaul lines. The backhaul lines may be configured in accordance with any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Hence, the plurality of BSCs 275 can be included in the system as shown in FIG. 3.

Each base station 270 may include one or more sectors, each sector having an omnidirectional antenna or an antenna pointed in a particular direction radially away from the base station 270. Alternatively, each sector may include two or more different antennas. Each base station 270 may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum (e.g., 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency assignment may be referred to as a CDMA channel. The base station 270 may also be referred to as a Base Station Transceiver Subsystem (BTS). In some cases, the term “base station” may be used to refer collectively to a BSC 275 and at least one base station 270. The base stations may also be denoted as “cell sites.” Alternatively, individual sectors of a given base station 270 may be referred to as cell sites.

Still referring to FIG. 2A, a broadcasting transmitter (BT) 295 may transmit a broadcast signal to the mobile terminals 100 operating within the system. The broadcast receiving module 111 (FIG. 1) is typically configured inside the mobile terminal 100 to receive broadcast signals transmitted by the BT 295.

FIG. 3 further depicts several Global Positioning System (GPS) satellites 300. Such satellites 300 facilitate locating the position of at least one of plural mobile terminals 100. Two satellites are depicted in FIG. 2, but it is understood that useful position information may be obtained with greater or fewer satellites than two satellites. The GPS module 115 (FIG. 1) is typically configured to cooperate with the satellites 300 to obtain desired position information. It is to be appreciated that other types of position detection technology, (i.e., location technology that may be used in addition to or instead of GPS location technology) may alternatively be implemented. If desired, at least one of the GPS satellites 300 may alternatively or additionally be configured to provide satellite DMB transmissions.

During typical operation of the wireless communication system, the base station 270 receives sets of reverse-link signals from various mobile terminals 100. The mobile terminals 100 are engaging in calls, messaging, and executing other communications. Each reverse-link signal received by a given base station 270 is processed within that base station 270. The resulting data is forwarded to an associated BSC 275. The BSC 275 provides call resource allocation and mobility management functionality including the orchestration of soft handoffs between base stations 270. The BSCs 275 also route the received data to the MSC 280, which then provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN 290 interfaces with the MSC 280, and the MSC 280 interfaces with the BSCs 275, which in turn control the base stations 270 to transmit sets of forward-link signals to the mobile terminals 100.

Hereinafter, description will be given of a method of acquiring location information related to the mobile terminal using a wireless fidelity (WiFi) positioning system (WPC), with reference to FIG. 2B.

A WiFi positioning system (WPS) 300 refers to a technology of positioning the mobile terminal 100 using a WiFi module provided in the mobile terminal 100 and wireless access points (AP) 320 for transmitting or receiving wireless signals to or from the WiFi module, namely, a wireless local area network (WLAN)-based positioning technology using WiFi.

The WPS 300 may include a WiFi location determination server 310, a mobile terminal 100, wireless APs 320 accessed to the mobile terminal 100, and a database 330 for storing random wireless AP information.

The WiFi location determination server 310 may extract information related to the wireless APs 320 accessed to the mobile terminal 100 based on a location information request message (or signal) of the mobile terminal 100. The information related to the wireless APs 320 accessed to the mobile terminal 100 may be transmitted to the WiFi location determination server 310 via the mobile terminal 100 or to the WiFi location determination server 310 via the wireless APs 320.

The information related to the wireless AP extracted based on the location information request message of the mobile terminal 100 may be at least one of MAC address, SSID, RSSI, channel information, privacy, network type, signal strength, and noise strength.

As such, the WiFi location determination server 310 may receive the information related to the wireless APs 320 accessed to the mobile terminal 100, compare the received information related to the wireless APs 320 with information stored in the pre-constructed database 330, and extract (or analyze) location information related to the mobile terminal 100.

Meanwhile, FIG. 2B has exemplarily illustrated that the wireless APs accessed to the mobile terminal 100 include first, second and third wireless APs 320. However, the number of wireless APs accessed to the mobile terminal 100 may variously change depending on a wireless communication environment where the mobile terminal 100 exists. The WPS 300 may execute positioning of the mobile terminal 100 when the mobile terminal 100 is connected to at least one wireless AP.

Hereinafter, the database 330 which stores random wireless AP information will be described in more detail. The database 330 may store various types of information related to random wireless APs located on different positions.

Examples of the information related to the random wireless APs stored in the database 330 may include MAC address, SSID, RSSI, channel information, privacy, network type, latitude/longitude coordinates of the wireless AP, a name of building where the wireless AP is located, the number of floors, detailed indoor location information (GPS coordinates available), an address and a phone number of an AP owner, and the like.

As such, since the database 300 stores the information related to the random wireless APs and the location information corresponding to the random wireless APs, the WiFi location determination server 310 may search for the wireless AP information corresponding to the information related to the wireless APs 320 accessed to the mobile terminal 100 from the database 330, extract the location information matched by the searched wireless AP information, and acquire location information related to the mobile terminal 100.

The acquired location information related to the mobile terminal 100 may be transmitted to the mobile terminal 100 through the WiFi location determination server 310. Accordingly, the mobile terminal 100 may acquire the location information.

Meanwhile, according to the present disclosure, information processed in the mobile terminal 100 may be displayed using a flexible display. Hereinafter, the flexible display will be described in more detail, with the accompanying drawings.

FIGS. 3A and 3B are conceptual views illustrating a flexible display 151 included in the mobile terminal 100.

As illustrated in FIGS. 3A and 3B, a flexible display 151 may include a display, which can be bent, curved, folded, or rolled by an external physical force applied. Here, the flexible display 151 may include both a general flexible display and an e-paper.

Here, the general flexible display refers to a display which is light and infrangile by being fabricated on a thin flexible substrate, which can be bent, curved, folded or rolled, like a paper, with still having display characteristics of the conventional flat panel displays.

Also, the e-paper uses a display technology to which characteristics of general inks are applied. The e-paper may be different from the general flat panel display in view of using reflected light. The e-paper may change pictures (drawing) or characters using a twist ball or electrophoresis using capsules.

In the meantime, the flexible display 151 may include a sensing unit 140 (see FIG. 1) thereon. The sensing unit 140 may sense bending-related information (or bending information) related to the flexible display 151. The term ‘bending’ disclosed herein may include meanings of ‘curving,’ ‘rolling,’ ‘folding,’ and the like.

The sensing unit 140 may be disposed overall or partially on the flexible display 151, and sense the bending information about the flexible display 151. Here, the bending information of the flexible display 151 may include a direction, a level, a position and a time that the flexible display is bent, an acceleration that the flexible display bent is restored to its original state, and the like. In addition, the bending information may be various information sensible due to the flexible display being bent.

The controller 180 may also change information displayed on the flexible display 151 or generate a control signal for controlling a function of the mobile terminal, based on the bending information on the flexible display 151 sensed by the sensing unit 140.

For example, referring to FIGS. 3A-(A) and 3A-(B), when the flexible display 151 is bent by an external physical force, the controller 180 may rearrange, divide, combine or change a curve of a screen image, which has been previously displayed on the flexible display 151, based on the bent direction, the bent angle, and a restoring acceleration to the original state of the flexible display 151.

As one embodiment, referring to FIGS. 3A-(A) and 3A-(B), when the flexible display 151 is bent inwardly by an external physical force, the controller 180 may display a screen image displayed on the flexible display 151 to be adjacent to each other. As another embodiment, when the flexible display 151 is bent outwardly by an external physical force, the controller 180 may display the screen image displayed on the flexible display 151 to be spaced from each other.

Besides, the controller 180 may control the method of displaying information on the flexible display 151 in various manners such that a user can accurately recognize the information displayed on the flexible display 151 in response to the flexible display 151 being bent.

Referring to FIG. 3B, the mobile terminal 100 may include a case which surrounds the flexible display 151. The case may be configured to be bent together with the flexible display 151 by an external physical force, taking in account the characteristic of the flexible display 151.

Meanwhile, as aforementioned, the controller 180 may generate the control signal related to the function of the mobile terminal 100 in correspondence with the bending information related to the flexible display 151.

As described above, the mobile terminal 100 is evolving into designs of various shapes. Accordingly, the flexible display is getting highlighted in view of a light weight and an infrangible property. The flexible display may derive creation of new user interface areas to which the conventional glass substrate-based displays have been limitedly applied or unable to be applied. As the flexible display is highlighted, needs of user interfaces using the properties of the flexible display are increasing.

Hereinafter, description will be given of the mobile terminal 100, capable of improving user convenience in displaying screen information on a display 151 of the mobile terminal 100, which is worn around a user's wrist, and a control method thereof, with reference to the accompanying drawings.

FIG. 4 is a flowchart illustrating a control method for a mobile terminal 100 in accordance with one exemplary embodiment of this specification. The mobile terminal 100 may include a display 151 (see FIG. 1), a sensing unit 140 (see FIG. 1), and a controller 180 (see FIG. 1). Here, the display 151 may include a flexible display and other types of displays.

Referring to FIG. 4, flatness of a wrist and a direction that the wrist faces may be sensed (S110).

A body of the mobile terminal 100 may be implemented into a shape of surrounding (covering, being worn on) the wrist using the bendable characteristic of the flexible display 151.

The sensing unit 140 may include a flatness sensing sensor which is disposed on one surface of the display 151 to measure the flatness of the wrist in real time or by a preset time interval.

Also, the sensing unit 140 may include a sensor which measures the direction that the wrist faces in real time or by a preset time interval.

As one embodiment of sensing the direction that the wrist faces, the sensing unit 140 may include a motion recognition sensor (not shown). The motion recognition sensor may include at least one of a terrestrial magnetism sensor, a gyro sensor and an acceleration sensor.

The terrestrial sensor may be a sensor which detects a direction and a size of a terrestrial magnetism, and generates an electric signal using the detected results. The gyro sensor may be a sensor which detects a rotation speed of the main body and generates an electric signal using the detected rotation speed. The acceleration sensor may be a sensor which measures a direction of gravity acceleration, detects an acceleration variation in one direction, and generates an electric signal using the measured and detected results.

Accordingly, the sensing unit 140 may sense whether or not the wrist is rotated. That is, the sensing unit 140 may detect displacement in response to the rotation of the wrist, namely, a rotation direction and a rotation angle of the wrist, and generate an electric signal using the detected displacement. By detecting the rotation direction and the rotation angle of the wrist, the sensing unit 140 may sense a direction that the body covering the wrist faces.

As another embodiment of sensing the direction that the wrist faces, the sensing unit 140 may include an eye search element (not shown). The eye search element may search for a user's eyes using at least one of a camera sensor 121 (see FIG. 1) and an infrared sensor (not shown). The camera sensor may be provided in plurality.

In detail, infrared ray emitted from the infrared sensor may be reflected on the retina of the user's eye within a predetermined viewing range based on the display 151. The reflected ray may be input into the eye search element. Afterwards, the eye search element may search for the user's visual field using the input infrared ray or a user image obtained by the camera sensor 121. Accordingly, the sensing unit 140 may sense at which portion of the display 151 the user is looking.

As another embodiment of sensing the direction that the wrist faces, the sensing unit 140 may include a light sensor (not shown). The light sensor may sense external light and detect a portion of the display 151 that faces the ground.

Afterwards, a display area on which screen information is to be displayed on the display 151 may be selected based on the sensed flatness of the wrist and the direction that the wrist faces (S120).

The controller 180 may select the display area for displaying the screen information on the display 151 by considering both the sensed flatness of the wrist and the direction that the wrist faces. In detail, the controller 180 may change a position, a size and a shape of the display area for displaying the screen information.

In addition, when a movement of the wrist is sensed after the screen information is displayed on the display area, the controller 180 may change the display area for displaying the screen information on the display 151 by considering both the flatness of the wrist and the direction that the wrist faces, which are newly sensed by the sensing unit 140.

Also, the controller 180 may control the display 151 to change the display direction of the screen information displayed on the display area according to the direction that the wrist faces. Accordingly, the controller 180 may display the screen information in a portrait type or a landscape type according to the direction that the wrist faces.

As described above, the mobile terminal 100 according to the one exemplary embodiment may decide the display area for displaying the screen information on the display 151 based on the flatness of the wrist. Accordingly, the mobile terminal 100 may display the screen information on the flat portion of the display 151, thereby reducing distortion of the screen information.

Also, the mobile terminal 100 according to the another exemplary embodiment may decide the display area for displaying the screen information on the display 151 based on the direction that the wrist faces. Accordingly, the mobile terminal 100 may display the screen information on the portion that the user faces on the display 151 by considering the user's eyes. This may result in improvement of user convenience.

FIG. 5 is a conceptual view illustrating an exemplary operation that the display area to display the screen information changes according to the direction that the wrist faces. FIG. 6 is a conceptual view illustrating an exemplary operation that the display direction of the screen information changes according to the direction of the wrist faces.

As illustrated in FIG. 5A and FIG. 6A, the controller 180 may select a display area 251 on which screen information is to be displayed on the display 151 based on the flatness of the wrist and the direction that the wrist faces, both sensed by the sensing unit 140. In detail, the controller 180 may select a position, a size and a shape of the display area 251. Accordingly, a flat portion of the display 151 within the viewing range of the user's eyes may be decided as the display area 251.

For example, as illustrated, in a state that a lower side of the wrist faces the ground, a flat portion of an upper side of the wrist may be decided as the display area 251. The controller 180 may display screen information 261 on the decided display area 251. Here, the screen information 261 may indicate every information displayed on at least partial area of the display 151.

Here, referring to FIG. 5B, when a movement of the wrist is sensed, the controller 180 may change the display area 251 for displaying the screen information 261 on the display 151 based on the flatness of the wrist and the direction that the wrist faces, newly sensed by the sensing unit 140.

For example, as illustrated, when a right side of the wrist faces the ground in response to the movement of the wrist, the flat portion within a left side of the wrist may be newly decided as the display area 251. Accordingly, the controller 180 may display the screen information 261 on the newly decided display area 251.

Referring to FIG. 6B, when the direction that the wrist faces has been changed in response to the movement of the wrist sensed, the controller 180 may change the display direction of the screen information 261 displayed on the display 151 based on the newly sensed direction that the wrist faces.

For example, as illustrated, when the wrist is rotated by a preset angle (for example, 90°), the controller 180 may rotate the display direction of the screen information 261 by the preset angle (for example, 90°). Accordingly, the controller 180 may change the display direction of the screen information 261 to face the ground.

Although not shown, the controller 180 may recognize the user's eyes to detect a viewing direction and a viewing angle of the user's eyes. Afterwards, the controller 180 may change the display direction of the screen information 261 based on the detected information. Accordingly, the screen information 261 may be displayed in a diagonal shape.

FIG. 7 is a conceptual view illustrating an exemplary operation of the display 151 when a touch input is sensed on a status display bar 264 displayed on the display 151.

As illustrated in FIG. 7A, the display 151 may display a status display bar. The status display bar may also be referred to as a status bar 264, and refer to a message line that indicate a current operation status of the mobile terminal 100.

The controller 180 may display first screen information 261 on a first display area 251. The controller 180 may display the statue bar 264 on one side surface of the first display area 251 in a fixed state. As illustrated, the status bar 264 may be displayed on an upper side of the first display area 251.

If another display area has been set in addition to the first display area 251 where the first screen information 261 is displayed, the status bar 264 may be continuously displayed only on one side of the first display area 251. For example, when a second display area 252 is set on one area adjacent to the first display area 251 and second screen information 262 is displayed on the second display area 252, the status bar 264 may be continuously displayed on one side of the first display area 251 without being displayed on the second display area 252.

Referring to FIG. 7B, when a touch input is sensed on the status bar 264, the controller 180 may display the second screen information 262 related to the status bar 264 on the first screen region 251. Here, the second screen information 262 may refer to screen information indicating a current operation status of the mobile terminal 100 in detail.

Simultaneously, the controller 180 may select one area adjacent to the first display area 251 as the second display area 252. The controller 180 may then display the first screen information 261, which has been displayed on the first display area 251, on the second display area 252.

FIG. 8 is a conceptual view illustrating an exemplary operation that an operation involved with screen information is controlled according to the movement of the wrist.

The controller 180 may control an operation involved with the first screen information 261 displayed on the first display area 251, in response to the movement of the wrist sensed by the sensing unit 140.

For example, referring to FIG. 8A, the controller 180 may display the first screen information 261 on the first display area 251. Here, the first screen information 261 may include an execution screen of a music player application. As illustrated, the controller 180 may display a playback screen 261 for a currently played music (for example, a first music) on the first display area 251.

Here, referring to FIGS. 8B and 8C, when the wrist is rotated by a preset angle in a preset direction (for example, a first direction) and thereafter rotated back, the controller 180 may playback a second music, which is the following music of the currently played first music in a playback list. Accordingly, referring to FIG. 8C, the controller 180 may display a playback screen 261′ for the second music on the first display area 251.

As such, the controller 180 may control an operation involved with the first screen information 261 displayed on the first display area according to the rotation direction of the wrist. That is, the controller 180 may decide whether to playback a previous music or the next music of the currently played music according to the direction that the wrist is rotated. Similarly, although not shown, in a state that a video playback screen is displayed on the first display area 251, the controller 180 may decide whether to playback a previous video or the next video of a currently played video according to the direction that the wrist is rotated.

As another example, although not shown, when an image is displayed on the first display area 251, the controller 180 may decide whether to delete the image or enter a folder including the image according to the direction that the wrist is rotated.

Also, when a webpage is displayed on the first display area 251, the controller 180 may decide whether to display a previous page or the next page of the currently displayed webpage according to the direction that the wrist is rotated.

When a call signal reception screen is displayed on the first display area 251, the controller 180 may decide whether to receive a call signal or deny the reception of the call signal according to the direction that the wrist is rotated.

When the first screen information 261 is displayed on the first display area 251 and a section is selected from the first screen information 261, the controller 180 may decide whether to copy or crop the selected section according to the direction that the wrist is rotated.

In addition, the controller 180 may control the operation associated with the first screen information 261 displayed on the first display area 251 according to a rotation angle of the wrist. Here, the display 151 may display an image object indicating the rotation angle of the wrist.

FIG. 9 is a conceptual view illustrating an exemplary operation that a display area to display screen information changes according to a touch input onto the display 151.

The controller 180 may select a touch point as a display area based on a touch input sensed on the display 151. When a plurality of touch inputs are sensed on a plurality of points of the display 151, the controller 180 may select the plurality of touch points as a plurality of display areas. The controller 180 may display the same screen information on the plurality of display areas.

Referring to FIG. 9A, the controller 180 may display first screen information 261 on a first display area 251. Here, when a plurality of touch inputs (hereinafter, referred to as ‘first and second touch inputs’) are sensed on a plurality of points (hereinafter, referred to as ‘first and second points’), referring to FIG. 9B, the controller 180 may select the first point of the first display area 251, to which the first touch input has been applied, as the first display area 251 and display the first screen information 261 on the first display area 251.

Referring to FIG. 9C, the controller 180 may select the second point of the display 151, to which the second touch input has been applied, as a second display area 252, and display the first screen information 261 on the second display area 252.

As described, the same screen information may be displayed on the plurality of touch points of the display 151, which may allow the user to share the same screen information with another party.

FIGS. 10 to 12 are conceptual views illustrating an exemplary operation of the display 151 when a touch input is sensed on the display 151 during multitasking.

As illustrated in FIG. 10A, the controller 180 may display the first screen information 261 on the first display area 251. The first screen information 261 may include a home screen.

In accordance with this exemplary embodiment of the present disclosure, the mobile terminal 100 may execute a multitasking function. The term ‘multitasking’ disclosed herein refers to simultaneously executing a plurality of applications. The plurality of applications may be applications which are linked to one another or independent of one another. That is, the multitasking is not limited to accompanying with or compensating for one application but refers to simultaneously executing several independent applications which have the same level. Here, the application indicates one of various additional functions, such as an Online service, a message function, a call function, a camera function, a playback of video or music files, and the like.

For example, the term ‘being executed’ or ‘being performed’ refers to a state before an application is terminated after the application is executed. The term ‘activation’ of an application refers to a state that an application which is being executed is displayed on a foreground other than a background of the display. On the other hand, the term ‘deactivation’ of an application refers to a state that an application which is being executed is displayed on the background other than the foreground of the display.

Referring back to FIG. 10A, the controller 180 may display the first screen information 261 including a home screen on the first display area 251. Although not shown, the controller 180 may display on the first display area 251 the first screen information 261, which includes an execution screen of an application, which is being executed on the foreground, while a plurality of applications are multitasked.
